Abstract
Purpose This study aimed to investigate the effect of Marshall ethanol infusion (VOM-Et) in the vein on mitral isthmus (MI) ablation. Methods Patients with persistent atrial fibrillation (AF) were grouped into vein of VOM-Et combined with radiofrequency (RF) ablation (VOM-Et-RF) and RF groups. The primary outcome was MI block immediate block rate after surgery. Stratified analysis was also performed for factors affecting the outcome measures. Results A total of 118 consecutive patients underwent AF ablation at Taizhou Hospital of Zhejiang Province from January 2018 to December 2021. Successful bidirectional perimitral block was achieved in 96% of patients in VOM-Et-RF (69 of 72) and in 76% of patients in the RF group (35 of 46) (P < 0.01). In the subgroup analysis, male sex, elder than 60 years, Left atrial diameter <55 mm, and AF duration <3 years were associated with the benefits of VOM-Et in AF Patients. Conclusion The vein of Marshall ethanol infusion for catheter ablation can improve the MI block rate. Male sex, elder age, smaller Left atrial diameter and shorter AF duration may have significant benefits for VOM-Et.

Abstract
A 55-year-old man who suffered from acute myocardial infarction complicated with cardiogenic shock was administered veno-arterial extracorporeal membrane oxygenation. Ultra-high pre-membrane lung oxygen saturation of 93% was observed. Transthoracic echocardiography revealed the presence of patent foramen ovale. The four-chamber view showed that the tip of the cannula was located in the patent foramen ovale, which resulted in a left-to-right shunt. Without adjusting the position of the drainage cannula, the patient was weaned from extracorporeal membrane oxygenation at 136 hours after initiation and survived to hospital discharge.

Abstract
Objective:To further recognize the clinical characteristics of non-syndromic enlarged vestibular aqueduct through the retrospective analysis of cases, with the purpose of providing references for clinical diagnosis and treatment. Method:Collect 54 cases of non-syndromic enlarged vestibular aqueduct, and analyze their clinical characteristics after history taking, physical examination, audiometry and imaging examination. Measure the biggest width of midpoint between internal and external of vestibular aqueduct on temporal bone thin-section CT, and analyze the relationship between the pipe width and sides of ear, types of hearing loss and degree of hearing loss through t test. Result:All 54 patients with non-syndromic enlarged vestibular aqueduct had bilateral ear involvement. There were 42 cases with prelingual deafness, 12 cases with postlingual deafness, and there were 38 ears with severe deafness, 70 ears with profound deafness. Ninety-six ears of hearing loss showed sensorineural deafness, and 12 ears manifested mixed deafness. The biggest width of midpoint between internal and external of vestibular aqueduct spread over 1.60-3.90 mm, and the average was 2.60 mm. There were no significant differences in data between left and right sides, degree of hearing loss and type of hearing loss. Conclusion:Non-syndromic enlarged vestibular aqueduct mainly manifests serious sensorineural deafness, and the diagnosis depends on imaging examination. There is no difference in the degree of expanding between left and right ear, and the extent of enlargement is not related to the type and the severity of hearing loss.

Abstract
BACKGROUND Heart failure (HF) is a major cause of morbidity and mortality worldwide, but current treatment modalities cannot reverse the underlying pathological state of the heart. Gene-based therapies are emerging as promising therapeutic modalities in HF patients. Our previous studies have shown that recombinant adeno-associated viral (rAAV) gene transfer of Sarco-endoplasmic reticulum calcium ATPase (SERCA2a) can be effective in treating rats with chronic heart failure (CHF). The aim of this study was to examine the effects of SERCA2a gene transfer in a large HF animal model. METHODS HF was induced in beagles by rapid right ventricular pacing (230 beats/min) for 30 days. A reduced rate ventricular pacing (180 beats/min) was continued for another 30 days. The beagles were assigned to four groups: (a) control group (n = 4); (b) HF group (n = 4); (c) enhanced green fluorescent protein group (n = 4); and (d) SERCA2a group (n = 4). rAAV1-EGFP (1 x 10(12) microg) and rAAV1-SERCA2a (1 x 10(12) microg) were delivered intramyocardially. SERCA2a expression was assessed by Western blotting and immunohistochemistry. RESULTS Following 30 days of SERCA2a gene transfer in HF beagles its protein expression was significantly higher than in the HF group than in the control group (P < 0.05). Heart function improved along with the increase in SERCA2a expression. Left ventricular systolic function significantly improved, including the ejection fraction, left ventricular systolic pressure, maximal rate of rise of left ventricular pressure (+dp/dt(max)), and the maximal rate of decline of left ventricular pressure (-dp/dt(max)) (P < 0.05). Left ventricular end-diastole pressure significantly decreased (P < 0.05). The expression of SERCA2a in the myocardial tissue was higher in the SERCA2a group than in the HF group (P < 0.05). CONCLUSIONS Intramyocardial injection of rAAV1-SERCA2a can improve the cardiac function in beagles induced with HF. We expect further studies on SERCA2a's long-term safety, efficacy, dosage and the optimization before using it in humans with HF.

Abstract
OBJECTIVE Overexpression of SERCA2a could improve cardiac function in human and experimental heart failure (HF) models. We observed the proteomics changes post SERCA2a overexpression in a pacing induced HF model in dogs. METHODS Beagles were divided into four groups: control group, HF group (230 beats/min for 4 weeks), HF + EGFP group (myocardial injection of 1 x 10(12) v.g recombinant adeno-associated virus carrying enhanced green fluorescent protein gene, rAAV2/1-EGFP) and HF + SERCA2a group (myocardial injection of 1 x 10(12) v.g recombinant adeno-associated virus carrying SERCA2a gene, rAAV2/1-SERCA2a). Thirty days after gene transduction, left ventricular systolic and diastolic functions were measured by echocardiography and invasive hemodynamics in all animals. By use of 2-dimensional gel electrophoresis (2-DE), -500 distinct protein spots were detected in myocardium of all animals. Protein spots observed to be altered between failing and SERCA2a overexpressed hearts were subjected to tryptic peptide mass fingerprinting for identification by MALDI-TOF mass spectrometry in combination with LC/MS/MS analysis. RESULTS At 30 day after gene transfer, HF signs were significantly reduced, cardiac function [LVSP: (214.72 +/- 31.74) mm Hg (1 mm Hg = 0.133 kPa) vs. (139.32 +/- 36.79) mm Hg, +dp/dt(max): (6779.43 +/- 217.58) mm Hg/s vs. (2746.85 +/- 931.23) mm Hg/s and -dp/dt(max): (-4341.42 +/- 322.02) mm Hg/s vs. (-2531.14 +/- 616.15) mm Hg/s, LVEDP: (21.86 +/- 6.95) mm Hg vs. (59.78 +/- 6.92) mm Hg] significantly improved in HF + SERCA2a dogs than those in HF + EGFP group(all P < 0.05) and parameters were comparable between HF + SERCA2a and control groups. We identified alterations in the expression level of more than 10 proteins in myocardium. These protein changes were observed mainly in two subcellular compartments: the cardiac contractile apparatus and metabolism/energetics. CONCLUSION These results showed that overexpression of SERCA2a could improve cardiac function accompanied with numerous alterations in protein expressions involved in calcium handling, myofibrils, and energy production in this dog model of chronic heart failure.
